Not always.
Diet-related deficiency may sometimes be treated with oral vitamin B12, while people who cannot absorb B12 normally may require a different treatment approach. NICE guidance recommends choosing oral or intramuscular replacement according to the underlying cause and clinical circumstances.
Taking supplements without investigating persistent neurological symptoms can also delay diagnosis of another condition.
Food Sources of Vitamin B12
Foods naturally containing B12 include:
Fish and seafood
Beef and other meats
Poultry
Eggs
Milk
Yogurt
Cheese
People who avoid animal products can obtain B12 from appropriately fortified foods or supplements.
Importantly, increasing dietary intake will not necessarily correct a deficiency caused by poor absorption.
Why Early Recognition Matters
Vitamin B12 deficiency is often treatable, particularly when identified early.
